ChefWorthy

ChefWorthy

By ChefWorthy

ChefWorthy is a review platform for commercial kitchen equipment. Ratings and reviews come from chefs and restaurant operators who use the equipment on the line. This connector lets Claude search a catalog of about 12,800 commercial foodservice products, read operator reviews, compare models side by side, rank brands within a category, and find local dealers and service companies by ZIP code. All of that works without a ChefWorthy account. With a free ChefWorthy account, Claude can also save equipment to your lists, record equipment you own in My Kitchen, and submit your own star ratings and written reviews. Reviews are only submitted when you ask, must be your own first-hand experience, and go through the same moderation as reviews written on chefworthy.pro. List prices are manufacturer or catalog list prices and can differ from dealer quotes.

Cheméo, Chemical and Physical Properties

Cheméo, Chemical and Physical Properties

By Céondo GmbH

Cheméo gives your agent direct access to thermophysical property data for chemical compounds: critical constants, vapor pressure, heat capacity, enthalpies of formation, fusion and vaporization, density, viscosity, surface tension, flash points and flammability limits, and around 130 properties in total. Search by name, formula, CAS number, InChI or SMILES. Temperature- and pressure-dependent properties come back as full data tables rather than a single number, so a correlation can be fitted or a value read at the condition you actually care about. Every value carries its literature source, which matters when the result ends up in a design calculation or a safety review. For molecules the database doesn't hold, sixteen of the most-used properties — critical point, normal boiling and melting points, acentric factor, enthalpy of vaporization, log P, water solubility and others — can be estimated from structure. UNIFAC, UNIQUAC and Joback group assignments are available for compounds that have them, for use in activity-coefficient and group-contribution work.

Cherami

Cherami

By Cherami

Give recurring work its own email address. Cherami lets Claude create a dedicated inbox where collaborators can send updates, questions, and documents without adding that correspondence to your personal mailbox or learning another tool. For a project with regular updates, ask Claude to gather what has arrived, read the attached documents, and follow up with contributors about missing details. Set the assignment and its boundaries upfront so Claude can handle routine correspondence using information you provide. When you want to review a message first, ask it to save a draft. Ask Claude to check in whenever you need an update, or configure an automation to check mail on a schedule. Cherami is currently free, with inbox and sending allowances. Sign in to Cherami to connect and give your next project an address.

CherryDrop

CherryDrop

By Maurice-Benjamin Huschke

CherryDrop is your personal inbox for everything you find while working with AI. Save notes, links, code snippets, and files into your private CherryDrop account straight from the conversation, then search and revisit them any time from the web app or from another AI agent. CherryDrop also lets agents share working context: store a named context with a summary and attached drops, then load it again in a different agent to continue exactly where you left off. All tools operate exclusively on the signed-in user's own data. Access is authenticated via OAuth 2.1 (authorization code + PKCE) and enforced with row-level security, so no tool can read or write another user's data.

Chess by Max Health

Chess by Max Health

By Max Health Inc.

Chess by Max Health lets people play and study chess inside ChatGPT. Players can start a single-player game against the built-in Stockfish engine at a chosen difficulty (Beginner to Maximum) or against the conversation model, with selectable color and time controls, and can join a live multiplayer lobby to play other people (with optional ranked ELO and match history for signed-in Max Health users). The same Stockfish engine analyzes games: per-move accuracy, blunders and inaccuracies, the turning points, and the time spent on each move, shown on an interactive board the user can step through. Games to analyze can come from the current session, a signed-in user's stored matches, or any public chess.com or Lichess username fetched live. Single positions can also be evaluated for the best move and main line, and key positions can be illustrated on a board with the recommended move and an evaluation bar.

Chessigma

Chessigma

By Chessigma

Ask Claude about chess openings, positions, games, puzzles and ratings. Every tool is read-only and needs no account. Opening guides: name an opening, such as the Sicilian Defense, Caro-Kann, London System, Queen's Gambit, Italian Game, Ruy Lopez, French Defense or King's Indian Defense, and get Chessigma's guide: the main line, up to four key variations with the idea behind each, the strategy for White and for Black, strengths and weaknesses. Popular openings have a full guide; any of about 3,700 named lines returns its name, ECO code and moves. What opening is this? Paste moves or a PGN to get the opening's name and ECO code, how far it followed known theory and the first move that left it. Positions and games: give a FEN to get the side to move, whether it is check, checkmate or stalemate, every legal move and the material count. Paste a PGN for a summary of the players, the result, the opening and how the game ended. Share a Chess.com live game or Lichess game link to get a link to its move-by-move review on chessigma.com. Daily chess puzzle: get today's puzzle, or any day's since 1 January 2024, with its position, rating and side to move, and solve it in the chat. Elo calculator: estimate a rating change after one game with the Elo formula, with K-factor defaults for FIDE, Chess.com and Lichess. Chess.com and Lichess use Glicko ratings, so their real changes differ. The tools do not run a chess engine. They state facts from the rules of chess, an opening catalogue and Chessigma's puzzle archive. For engine analysis, answers link to the Chessigma analysis board, where Stockfish runs in the browser.

Child Support by Province

Child Support by Province

By Child Support by Province

Child Support by Province lets Claude give Canadian parents the exact monthly child support amount from the official Federal Child Support Tables, instead of an estimate from memory. Ask in plain words, for example "How much child support is there in Ontario on $85,000 for two kids?", and the connector returns the table amount for the province or territory where the paying parent lives, using the 2025 tables in force since October 1, 2025. It covers all 10 provinces and 3 territories, one to six or more children, and incomes above $150,000. It also handles shared parenting (each parent at least 40% of the time, where the two table amounts are set off against each other) and special or extraordinary expenses such as daycare, which are shared in proportion to income. For Quebec it says when the Quebec model applies instead of the federal table. Every answer explains the rule it used and links to the full breakdown on ChildSupportByProvince.com. The tables were checked cell by cell against the Department of Justice Canada PDFs. Read only. No sign in. The connector never asks for names or contact details and does not store the questions it receives. Estimates only, not legal advice. ChildSupportByProvince.com is independent and not affiliated with the Government of Canada.

Child support (Quebec)

Child support (Quebec)

By mmcco

Child support (Quebec) estimates child support under the Quebec model for determining child support. - revenu_disponible isolates a parent's disposable income (income minus the 2026 base deduction and contributions). - calculer_pension_alimentaire runs the full calculation from both parents' incomes, the number of children, custody time and special expenses, using the official 2026 fixation table. - expliquer_modele explains a given aspect (method, disposable income, custody, expenses, ceiling, indexation, limits). This is an estimate to understand and plan; the actual amount is set by the court or SARPA. It is not legal advice, and no figure or rule is invented - the table and method come from the official Quebec sources.

Chime Scheduler

Chime Scheduler

By Wednesday Solutions

Chime Scheduler is a free LinkedIn post scheduler for Claude. Write a LinkedIn post with Claude, say when it should go out in your own words ("Tuesday at 9am", "tomorrow morning"), and it is published on your LinkedIn profile at that time. Chime Scheduler turns your words into an exact time in your time zone and echoes it back, so you can catch a wrong time before anything goes live. Plan your LinkedIn content calendar without leaving the chat: - Schedule LinkedIn posts for later, or save them as drafts. - Publish to LinkedIn right now and get the live post link back. - Add a first comment, such as a link, a few seconds after the post goes live. - Post images (up to 9) or one MP4 video: Claude gives you a private, single-use upload link, and you confirm the files in the chat before they are attached. - See your scheduled, draft and published LinkedIn posts, reschedule or edit any post that has not gone out yet, and cancel posts. - Check that your LinkedIn account is connected and when the login expires. How it works: you connect with Sign In with LinkedIn. Posts are published through LinkedIn's official API, only when you ask, and only on your own personal profile. Chime Scheduler never reads your LinkedIn feed, messages or connections. If a post can't go out (for example an expired LinkedIn login), it is held, never posted late without you choosing to, and Claude tells you what to do next. A "Your posts" page at schedule.getchime.co shows your LinkedIn posts outside the chat. Built for founders, consultants, recruiters, marketers and anyone growing a personal brand on LinkedIn with consistent posting.

China Footnotes

China Footnotes

By Will Wang

China Footnotes answers practical questions for first-time foreign visitors to China: opening hours, tickets, booking channels and passport notes, last entry, metro and taxi directions, stored notices, events and traveler tips. It also covers pre-trip setup: when to go, visas, paying, internet and SIM, apps, booking ahead, getting around and safety. Ask for a full entry or selected sections and fields. Traveler tips are paginated, with counts and more available on request. A visit date adds a conservative check against stored rules, not live opening or ticket availability. Facts retain conditions, sources and actual check dates; unknowns and conflicting sources remain explicit. Traveler reports stay separate from official rules. Read-only; no sign-in, bookings or sales. The service records bounded usage metrics and anonymous category aggregates. It does not retain raw search words, full tool inputs or outputs, conversations, visitor IPs or persistent user IDs. Do not include personal information in tool inputs.

Chiostro Legal Ai

Chiostro Legal Ai

By Chiostro

Chiostro is a legal research service for Italian lawyers and in-house counsel. It answers only from the sources it holds, and says which ones. With this connector Claude can: • Search the corpus: Italian codes and legislation, Constitutional Court decisions, tax and trial-court case law, EU Court of Justice and European Court of Human Rights decisions, and regulatory practice from ministries and authorities. Each result comes with its title, the link to the official publication and an excerpt of the actual text. • Ask for a reasoned answer on a point of Italian law. The answer is built only on the retrieved sources, carries numbered references [n], and its quotations are checked against the source text before delivery. • Check whether the provisions cited in a contract, pleading or memo are still in force, repealed or partly repealed, and by which act. This check is deterministic: no language model decides the verdict. Chiostro covers Italian and EU law. It does not search the web. Questions and answers are in Italian; the interface and this listing are also available in English. You need a Chiostro account (free trial or subscription). Questions asked through the connector count like questions asked in Chiostro; source searches have their own daily ceiling.
